Is there an earlier version of the software that will run on Windows Vista?
Although I have not tried it, I think that 0.9.2b (available in the older versions section of the downloads page) used to be the only one that worked on XP and thus might work on Vista. I’d start with the latest version and if that doesn’t work, install the next lower version til something does. You may need to install the C runtime libraries (search for the error message that you get in the forums, it is “missing api-ms-crt-runtime” and there are a lot of posts about what to load to fix it.
